Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...

Unravelling Electronic Structure and Molecular Vibrations of Proteins in Virus Using Novel Correlated Plasmon‐Enhanced Raman Spectroscopy With Machine Learning

Small, EarlyView.
A novel, non‐destructive, stable, direct technique, named correlated plasmon‐enhanced Raman spectroscopy (CP‐ERS), which is based on a newly‐developed highly oriented single crystalline gold quantum dots (HOSG‐QDs) chip, is developed to measure and quantify molecular vibrations and electronic structure of analytes.

Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

Small, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Ultrathin Freestanding MoSiN Nanocomposite Membranes as Efficient High‐Temperature Mid‐Infrared Thermal Emitters

Small, EarlyView.
Ultrathin freestanding MoSiN nanocomposite membranes are developed as stable and efficient mid‐infrared emitters for gas sensing under extreme thermal conditions. A 12 nm‐thick membrane combines intermetallic phases for enhanced IR absorption with a dielectric phase for mechanical stability.

Fast Switching and High Polarization in Ferroelectric Hf0.5Zr0.5O2 Films

Small Science, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 thin films are grown under tuned redox conditions to simultaneously achieve high polarization and fast switching. Control of defect dipoles and internal fields enables stable domain wall motion without compromising performance. This work provides a pathway for designing fast and energy‐efficient ferroelectric devices.

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Investigating Dynamic Characteristics of Cavitation in Insulating Oil Microgaps Under Vibration: Theoretical Analysis and Experimental Observation

High Voltage, EarlyView.
ABSTRACT The internal pressure fluctuations caused by vibration in oil‐immersed electrical equipment can initiate bubbles within narrow oil gaps, reducing the electrical strength of equipment and giving rise to the problem of abnormal gas production in oil‐immersed equipment.

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the
